XBS are the only Next Gen consoles with full Direct X 12U RDNA 2 features.

PS5 is the only Next Gen consoles with full PlayStation Shader Language RDNA 2 features.

From what I understand(I don't understand shit really, btw), putting aside Direct X, it was Mark Cerny's decision not to make it full RDNA 2 because some of the features are designed more for non gaming PC tasks, so he considered it redundant for a gaming console to include it/them, left it out to make room for more customized features that aren't in RDNA 2.

Don't ask me to elaborate, I don't really know what I'm talking about, I'm just a humble console peasant, and this is my interpretation of some of the things I've heard MooresLawIsDead say.

Customisations to hardware are a thing.
Sony have just customised their chips instead of useing full base AMD RDNA 2, they changed parts of it, to something they wanted instead.

This article about the xbox makes it sound like a fantastic thing, that its full RDNA2.
That could also mean "too lazy to try and improve" on AMDs design.
Maybe Sony wanted something differnt or better, and changed parts of the design.

This doesnt have to be a weakness.

This. People blowing this out of purportions, because of PR takes from a xbox site.

Yes, people ignore that customsation of chips isn't something new or unheard of in consoles.
You could take out a part of RDNA2 and change it to something you rather used instead (which there would be a reason for, otherwise why bother doing it?). It could be better off, for being customised differntly than full RDNA2, we dont know.

I'm sure that the PR article is "literally" right in some way that will be discovered soon (maybe number of compute cores they showed on screen, or GHz, or DirectX support). I'm also sure that AMD aren't maintaining multiple different versions of their GPU that differ in significant ways.

The consoles will be out in a couple of weeks, so we can put them side by side. My guess is they are going to as close to identical as we have ever seen two consoles...

It’s pretty amazing how over time the GitHub leak has turned out to be almost entirely accurate. GAF and Reeeeeee mods should be dining on crow for months. It also explains the delay in dev kits that people were rumored to be annoyed by earlier this year, MS was simply waiting for full RDNA2 support.

Obviously MS wants development between console and PC to be as simple as possible. Sony doesn’t have to worry or care about this. Will be interesting to see what differences this makes in multiplats down the line. Won’t make any differences at launch.

GAF is in full meltdown mode though.... amazing responses. Apparently MS is lying... and RDNA2 is “generic” anyway. Mind you this is coming from the same posters who for months were saying PS5 is the only RDNA2 console. Now that the shoe is on the other foot, RDNA2 is generic. When you’re bored, the thread there is worth a read lol

Some pretty pointless PR. Of course the PS5 doesn't support Microsoft's Direct Storage... of course PS5 doesn't support DirectX Ray Tracing.

They have their own custom versions. This is just PR fluff that people will use as ammunition for silly console wars.

I mean, its probably an advantage to devs who are used to PC, meaning Xbox versions might run slightly better then ps5 if its a game also on PC.

That being said, we don't know how well PS's solution will do VERSES the xbox's DX12 implementation so...

Can't give any credit at all to the 2019 rumour. The small difference in performance is entirely down to the number of CU's. Both are RDNA 2, the difference is PS5 implements custom versions of some of these technologies, so while MS can say that they have the only console supporting all the feature set that was on stage... well it's meaningless and obvious.

Obviously PS5 cannot support DirectX Ray Tracing, it doesn't use DirectX... a microsoft technology. Obviously it doesn't use Microsoft's Direct Storage either. So that's 2 parts of the RDNA 2 feature set PS5 is missing... but they have their own versions that may be equal or even surpass Microsoft's so... this isn't a win. This is a "we have different stuff" that's it. Different, not necessarily better or worse.

PS5 supports Ray Tracing (Custom version of DirectX Ray Tracing), PS5 has a blazingly fast SSD (Custom version of Direct Storage), PS5 also has it's own versions of Variable Rate Shading and Mesh Shading. It isn't missing features, it's using it's own versions.

As for 320w vs 350w I believe running more CU's at a lower clock speed like Xbox will be more power efficient than the PS5 running less CU's at higher clocks. There's also other areas where PS5 may require more power. It's SSD may use more, tempest audio engine, Wifi 6 over Wifi 5, and it even has an extra usb port (usb-c at that) over the Xbox Series X meaning a higher potential Watt Usage. (The extra USB-C port on it's own could account for 9 watts +).

320w vs 350w isn't indication that PS5 isn't using RDNA 2.

So in conclusion this is just a little bit of PR fluff that is being blown out of proportion. Microsoft uses the same implementations as they do on their PC so they support the same RDNA 2 feature set shown on stage at the event. PlayStation uses different implementations on their console.

This is not a better or worse, it's just a difference.

Power Supply does not equal Power Consumption.

The law of thermodynamics literally comes into play, essentially a Power Supply converts energy (I.E. 240v down to 12v) and in the process of doing so looses some energy during the conversion process... And every power supply has an efficiency curve.

So for example... An 80% efficient 400w power supply would actually draw 480w from the wall to deliver 400w, where-as a 90% efficient power supply would draw 440w from the wall.

Both deliver 400w.

And another aspect we need to keep in mind is that as a power supply begins to age, they actually do become less efficient, so console manufacturers need to build additional tolerance in the power supply to ensure that as it ages, it will still be able to provide the electrical needs over the long term.

In short... Please take the 350w vs 320w PSU as irrelevant, because ultimately it is.
What needs to happen is proper power draw analysis done on individual components... And that generally isn't happening until these devices are released.

Ray Tracing has been in video games for years, trust me, we have all seen it and experienced it to various degrees.
Hardware based Ray Tracing is taking it a big leap forwards.

It's really to early to tell what the fundamental differences are between RDNA 1.0 and 2.0 from a low-laying perspective anyway.

But even Microsoft's Xbox Series X has some significant deviation from known PC RDNA 2.0 GPUs, such as lacking an infinity cache.

From an end user perspective, pretty much.

Regardless if you have an Xbox Series S, Series X or a Playstation 5, you are going to have a fantastic time.

Mesh and Primitive Shaders are the same thing.
